Hi  !

That 'From Doc To PDF' is (as you probably already suspected) a browser hijacker, that you of course will want to get rid of.

Go to the 3-bar menu (or   'Tools') => Addons => Extensions and look for any unfamiliar or suspicious looking extensions, like e.g. :

SafeSearch Incognito SearchAssist Incognito Search for Fire Fox 1.6 SafeSearch ch SafeSearch net Converter.onesearch org File Convertor and Search Addon Findwide Search Engine 1.7

When you find any : remove them.

Do the same in Windows' Control Panel => Programs.

However :   most malware will be 'hiding' somewhere , so let's run malware scans :

Run most or all of the listed malware scanners.
They all work differently   -   what one program doesn't pick up, the other might.

My pleasure - I'm glad you rid of that 'nuisance'  !

I am so frustrated and confused. Somehow I made the mistake and now have that FromDOC to PDF. I can't find anything to delete. I've gone to Remove Programs, Run Scans from Spybot and Avast. I just can't believe I was stupid enough to end up having this terrible thing on my computer. I even followed a suggestion about going to About:Config and nothing there.

But EVERY time I open a new Tab up comes that From Doc to PDF page. I went to "Customize and found the option to add it to my Toolbar and did that thinking I could just delete it. NO!!

Is there any simple solution for me? I've checked my Add-Ons and nothing there either.

Is there a Registry item I need to delete. I'm leery about messing with the Registry. I would so appreciate a simple solution.

Thanks.
